    JOB INTERVIEWS

    hi guys! i just had a technical interview in a job interview. i was asked how will u study at night without using current and a combustible substance at your work place? answer:what about optical fiber cutting?

    Beta of the BJT

    hi audioguru! i carry out the Q point and hence the beta analysis for a transistor only in CE region. cause i use it mostly as my amplifier. for such a case i found the results which i just told.i too believe that a transistor is saturated when VCE is 0 i.e we move towards forward bias from...

    electrical and electronics

    hi all! i wish to know what is the demarkation line between electrical and electronics engineering? i.e to decide whether an application is a subject matter of electrical or electronics engineering?

    Plz Advice

    hi anita! i recently did an industrial project on embedded systems .actually i used an embedded system for a control application ...basically u must understand that they are nothing but compact,industry specific microcomputers used for control applications. i always liked to play with my C...

    Beta of the BJT

    hi audioguru! in saturation region i guess a transistor has a beta which is lower than its value in active region. for hard saturation beta in saturation ,beta in saturation is generally 10 times less than in active region.do u agree with this? base current is higher than usual once the...

    DIGITAL COMMUNICATION

    hi all! we generally talk about bits per second in digital transmission specially computer terminology. does bandwidth have no meaning here? shannons relation relates bandwidth to bit rate how does the relation comes? ;D

    Advice on Equivalent transistors

    some time spending and meddling up with data sheets and of course as audioguru said experience! ;D

    Digital mishaps

    hi audioguru! nowadays we have error correcting algorithms too. but regarding digital communication can u tell me what is bandwidth(in digital context)

    COILED RESDISTOR?

    hi audioguru! do u mean about the drops in the connecting wires in case the measured wire is long? ;Dyeah that may be the case and also it is inconvenient to handle ;D

    Beta of the BJT

    DATASHEETS LIST BETA IN THE SATURATION REGION......... it is a convention for all manufacturers.

    COILED RESDISTOR?

    we just used ohms law for it.i guess we generally coil up a wire to get more length into the ckt and hence higher resistance

    QUESTION

    hi dear! even if u measure the resistance or any qty using a meter u have to pass some current isnt it? ;D

    big projects on microcontroller or on software upto Rs.-10000

    vineet! i am afraid but u should have a very good hand at a programming language preferably C or C++.do u have ?

    COILED RESDISTOR?

    hi kevin! actually i was asking this because in our school days when we were asked to measure the resistance of a iece of wire our teacher always told us to coil it up.i dont understand even now why ? what difference does it make?  ;D

    Beta of the BJT

    HI GUYS!(kevin) and by default too if i say that beta of xyz transistor is say b,then b is the beta in active region when vce causes Ic to almost stabilize at a particular Ib. i guess datasheets also list the same ;D

    Beta of the BJT

    hi walid! beta of  a  transistor is determined as: setting up a known value of Vce for the transistor.in sinking mode apply the collector current of say 5mA.sense the base current and divide the values.u will get different betas for different VCEs........thats sure. ;D

    Like resistors coils

    hi guys! do we have color codes for all the 3 namely capacitor,inductor and resistor?

    COILED RESDISTOR?

    hi  all! i wish to know that if i have a wire piece and i just coil it up. what do i get an inductance or resistance?
